Park assist
Parking system
Applies to vehicles: with pa rking system
Different park assist systems may be used for
parking or maneuvering, depending on the
vehicle's features.
Parking system (rear)*:
For the parking system (rear), the acoustic
park assist system is installed in the rear of
the vehicle
¢ page 118.
The rear parking assist system uses ultrason ic
sensors to determine the distance of the vehi­
cle from a detected obstacle. There are a tota l
of four sensors located on the rear bumper
(two in the m iddle and two on the sides).
Parking system (rear, with rear view
camera)*:
For the parking system (rear, with rear view
camera),
the rear acoust ic park assist system
is integrated in the rear of the vehicle and the
rear view camera is integrated in the rear lid
¢page 121.
The parking system (rear, with rear view cam­
era)
uses ultrasonic sensors to determine the
distance of the vehicle from a detected obsta­
cle . There are a total of four sensors located
on the rear bumper (two in the middle and
two on the sides).
_& WARNING
Make sure the sensors are not covered by
stickers, deposits or any other obstruc­
tions as it may impair the sensor function.
For information on cleaning, refer to

Parking system (rear)
Rear acoustic park assist
Applies to vehicles: with parking system (rear)
The rear acoustic park assist warns you of ob­
stacles or objects behind your car .
Description
The rear acoustic parking assist system deter­
mines the distance of the vehicle from an ob­
stacle using ultrasonic sensors. There are 4
sensors in the rear bumper.
The range at which the sensors start to meas­
ure is
about:
To the sid e 2 ft (0 .60 m)
Center rear 5.2 ft (1.60 m)
Activation
Acoustic parking assist is activated automati­
ca lly when
reverse gear is engaged. A brief
tone confirms that the system is activated.
Warning tones
Distance warning is given by warn ing tones
wh ich are generated by the rear signa l genera­
tor. The volume and the pitch of th e warning
tones can be adjusted in the MMI*
¢page 119.
Reversing
Distance warning when reversing starts when
an obstacle is detected in the range of the
parking assist system . As the distance de­
creases, the time interval between the a udible
tones becomes shorter.
When the distance is less than 1ft (0.30 m),
the tone becomes continuous. At this point
you should stop backing up .
Please note that low objects already signalled
by a war ning can disappear from the system's
detection range and will not continue to be
signalled .
If the distance to an obstacle remains the
same, the vo lume of the distance warning is
gradually reduced after about 4 seconds (this
does not apply in the continous tone range).

Approaching another obstacle will result in
the distance warning sounding at the normal
volume aga in.
Malfunction s in the s ystem
If a war ning tone is audible for about five sec­
onds when you turn on the ignit ion, there is a
mal function in the system. Have the problem
corrected by your authorized Audi dealer.
Keep t he sensors in the rear bumper clean and
free from ice so t hat the acoustic park assist
system can function properly.
A WARNING
- Sensors have dead spaces in which ob­
jects cannot be detected. Be especially
alert for small children and animals ,
since they are not always detected by the
sensors.
- The acoust ic park ing system is not a sub­
st itute for the d river's own caut io n and
alertness . Ultimate responsib ility always
remains with the driver during park ing
and simi lar maneuvers. Always watch
where you are dr iving .
- You should always adjust the volume and
frequency of the warning tones so that
yo u can easily hear the a co ustic distance
warning even if the radio is p laying, the
air-conditioner blower is on High or there
is a high leve l of outside noise.
- Check the settings whenever anyone
else has driven the vehicle before you.
- Remember that low obstacles for wh ich
-
a war ning has a lready been issued may
"dive" below the system's sensing zone if
the veh icle is being backed up closer . In
th is case, the warn ing sound shutt ing off
does
not i ndi cate that you have cleared
the obs tacle. Instead, impact is immi­
nent .
- Objec ts such as trai ler hitches, c hains,
narrow posts or fences covered by a thin
l ayer of paint may not a lways be detect -
Park a ssis t 119
ed by the sys tem . They can still damage
your vehicle without warning.
(0 Tips
Keep the senso rs in the rear b umpe r clean
and free of snow and ice so that the acous­
tic parking assist system can function proper ly .

Sensors in the bumper
Sensors are located in the rear bumpers. If
these detect an obstacle, audible signals warn
you. The range at which the sensors begin to measure is approximately:
To the side 2 ft
(0.60
m)
Center rear 5.2 ft (1.60 m)
Distance warning when reversing starts when
an obstacle is detected in the range of the
parking assist system . As the d istance de­
creases, the time interval between the audible
tones becomes shorter .
When the distance is less than 1ft (0.30 m),
the tone becomes continuous . At this point
you should stop backing up .
If the distance to an obstacle stays the same,
the volume of the distance signal chime is
gradually reduced after about 4 seconds (does ..,.

Sw it c hing off
.,. Drive faster than 9 mph (15 km/h), or
.,. take the vehicle out of reverse gear. The
acoustic parking system is immediately de ­
activated, and the rear view camera picture
is deactivated automatically after a per iod
of about 15 seconds, or
.,. switch off the ignition.
The delay in deactivating the camera provides an uninterrupted view behind the vehicle es­
pec ially when maneuvering in tight parking
spaces and prevents the picture from turning
off the every time you sh ift out of reverse .
If the warning message appears in the display but not the rear view camera picture, read and
confirm the warning message. The acoustic
d istance signal is always active .
If you press a function button on the MMI
control console, the rear view camera picture
d isappears. The rear view camera picture reap­
pears the next time you park.
Further information on the warn ing message
and the MMI control console can be found in
the MMI instruction booklet .
A WARNING
-Only use the rearview camera to assist
you if it shows a good, clea r picture. For
example, the image may be affected by
the sun sh in ing into the lens, dir t on the
lens or if there is a defect .
- Use the rearview camera only with the
rear lid completely closed. Make sure any
objects you may have mounted on the
rear lid do not block the rearview cam­
era .
(D Tips
-The rear v iew camera picture is ava ila b le
as soon as the MM I Display or the MM I is
switched on, or the start-up phase is
completed.
- The sensors must be kept clean and free
of snow and ice for the park assist to op­
erate. -
